• Here is the take-home final exam. NOTE: As mentioned in class, there is an error on problem 2. The correct statement should be: "(i) among the points which are colored red, yellow, blue, and green, there do not exist any two points of the same color which are a distance of exactly TWO UNITS apart from each other. (ii) among the points which are colored purple and orange, there do not exist any two points of the same color which are exactly ONE UNIT apart from each other."
• Here are solutions to the problems on the midterm exam. Problems 1 and 2 were worth 20 points each, problems 3(i) and 3(ii) were worth 15 points each, problem 4(i) was worth 10 points, and problem 4(ii) was worth 20 points. The little numbers in circles written on the solutions are rough indications of how I assigned partial credit.
• Review sheet for the midterm exam.
